Please take a look at my question.
Users questions: I have an old computer configured as follows: AMDathlon700 Lenovo K7T motherboard memory hard drive 80G 256 graphics MX40064M Lenovo K7T motherboard manual said to AMDathlon1.1G and in the future to support a higher frequency of the CPU, but I would like to know Higher in the end is how much I want to upgrade CPU. Because I see rmvb format movies with point card (XP system), not aware of this need not? Or Is there any way to improve the performance of the old machine? I do not play games, let him play to heat!
Experts answer: Lenovo K7T motherboard, using V IAKT133 chipset, SocketA architecture, the maximum support AMDAthlonC1.3G (133 FSB), and so can not use the Barton 1600 + cpu, if KT133A on it. Secondary market is difficult to get the AthlonC1.3GC PU, will be more of a Athlon1G (100 FSB), 50. 700 than you have some performance, it is worth changing. Your memory cards can meet your requirements.
